Works fine yet inexpensive
I needed this to eliminate a ground loop hum between my PC and an external audio amp. Worked great. Note that there is a switch that must be flipped accordingly to lift the ground as needed. Audio quality seems fine since it’s only MP3 music. Probably wouldn’t buy this for a million dollar recording studio but for my needs, this was an economical choice.

Finally!
To say I was skeptical is an understatement. I plugged this in to the RCA input coming into my PS Audio AMP and the 60Hz hum/Buzz is completely gone. I mean completely gone. I replaced electrical outlets, replaced cable and still have major noise. I installed this FMUSER RCA Audio Ground Loop Isolator and my music system now is dead silent even when I turn the volume up and there is no music playing. Great device. Get one whenever they are back in stock! So happy here!

It did eliminate some hum noise, but ...
I purchased this for the humming noise in my car stereo. The installation is straightforward, but I could hardly tell the big difference between pre and post the installation. It might only happen to me.
